How to Plan for Outlets in a New Backsplash Installation

When installing a brand new backsplash, you have the advantage of putting outlets exactly where you want them. Here are some tips for optimal outlet placement when doing a backsplash:

Consider the Height of the Outlets

Standard outlet height is 18 inches from the floor. However, for a backsplash installation, you may want to place them slightly higher at around 24 – 36 inches above the ground. This puts them neatly in line with a 4 inch backsplash and avoids awkward tile cuts.

Locate Outlets Between Tile Grout Lines

Plan outlet placement so that they fall between tile grout lines. This minimizes any tile cuts or notches that need to be made.

Space Evenly Between Other Fixtures

Allow for even spacing between outlets, Appliances and fixtures. Groupings of outlets, switches and fixtures should have a balanced look.

Use Odd Number Groupings

When including multiple outlets or switches on one wall, use groupings of odd numbers rather than pairs for a more appealing look. For example, install 3 outlets instead of 2.

Allow Enough Height Above Countertops

Ensure receptacles have enough height above countertops, islands, and sinks per building codes. Usually outlets must be installed at least 12 inches above countertops.

With proper planning, you can have a functional and gorgeous backsplash full of outlets placed just where you need them.

Preparing to Tile Around Existing Outlets

Many backsplash installations will involve working around existing outlets, switches and receptacles. Here’s how to prepare them for your new tile job:

Turn Off Power at the Breaker

Safety first! Turn off power to the outlet at the breaker and use a non-contact voltage tester to double check that power is off before working.

Remove Cover Plates

Take off any cover plates to expose the electrical box and wires before you begin tiling.

Understand the Box Type

Determine if you have standard single gang boxes or more complex multi-gang boxes. Multi-section outlet boxes will require more precision when cutting tiles.

Check Box Position on Wall

Note if the existing boxes are centered on a tile grout line or if they fall in the middle of a tile. This will impact your tile layout options.

Clean Boxes

Vacuum and wipe down existing boxes to remove any dust, debris or grime on the receptacle.

Consider Box Extenders

If existing boxes are recessed deep in the wall, attach box extenders to bring them flush with the new tile.

Taking time to properly examine the electrical boxes will make for an easier tiling job later on.

How to Mark Tiles for Cutouts Around Outlets

Once you know the exact position of all your outlets and boxes, you can start marking tiles that will need cutouts. Here is the systematic process:

Make a Template from Cardboard

Trace the exact shape of the box on a piece of cardboard. This will be your template for tracing cutout lines.

Mark Tiles Before Installation

Dry lay rows of tile on a flat surface near the installation area. Use your template to trace cut lines on tiles that will surround boxes.

Use a Utility Knife to Score the Tile

Score cut lines with a sharp utility knife. Don’t try to cut all the way through the tile yet.

Consider Direction of Cutouts

Some outlet boxes may position the receptacles vertically while others horizontally. Mark the shape accordingly.

Allow Space for Outlet Cover Plates

Make cutout openings 1/8″ larger all around the box to leave room for cover plate installation later on.

Marking all your outlet tile cutouts ahead of time will make the actual tile installation go much faster.

Cutting Tile Around Electrical Boxes: Tools and Techniques

Carefully cutting tile around outlet boxes is crucial for getting a clean, professional look. Follow these tips on tools and techniques:

Use a Wet Saw for Straight Cuts

For simple straight line cuts, a wet saw is the best tool. The water keeps tiles cool and prevents cracking or chipping.

Use a Jigsaw for Curved Cuts

For intricate curved cuts, a jigsaw with a diamond tile blade is ideal. Move slowly and steadily.

Consider Using Tile Nippers

Nippers allow you to nibble away small pieces of tile for detailed cuts and notches around corners.

Make Relief Cuts First

Use a utility knife to score relief cuts just outside your finished cut line. This avoids cracking.

Cut Outside Lines First

Cut the perimeter shape first, then go back to cut the inner area of the hole. Less risk of tile damage.

Work Slowly and Carefully

Rushing leads to mistakes! Take it slow and steady as you cut around outlets for best results.

Smooth Any Rough Edges

Use a sharpening stone to carefully smooth any rough edges around cut tiles. This prevents injury and improves fit.

Don’t be afraid to take your time with the cutting process. Patience and the right tools will give you cutouts that look factory made.

Installing Tiles Around Outlets: Step-by-Step

Once your outlet tiles are properly marked and cut, you’re ready for installation. Follow these key steps:

Dry Fit Cut Tiles

Do a dry run by test fitting your cut tiles around the outlet boxes before applying any mortar. Make sure tiles fit correctly.

Apply Mortar for Surrounding Tiles First

Adhere uncut tiles in the area surrounding the outlets first. This provides a solid base.

Mortar Outlet Boxes

Apply a 1/4 inch layer of mortar on the back of electrical boxes before setting cut tile pieces.

Press Cut Tiles Into Mortar

With boxes mortared, carefully press cut tiles with outlet openings into position in the thinset.

Use Tile Spacers for Consistent Grout Lines

Insert tile spacers around outlet tiles for even spacing and straight grout line alignment.

Check for Movement or Gaps

Inspect outlet tiles closely to make sure there is no shifting or gaps before the mortar dries.

Allow Proper Curing Time

Let mortar fully cure for 24-48 hours before continuing with grouting process.

Taking it step-by-step ensures you won’t miss any important details when installing outlet tiles.

Grouting Seamlessly Around Electrical Boxes

Grouting around outlets finishes them off with a polished look. Here are some tips for great results:

Grout Vertical Sections First

On wider electrical boxes, grout the vertical sections between tiles surrounding the box first.

Use a Grout Bag for Detail Work

Switch to a grout bag for grouting immediately next to and around the outlet. More control than a grout float.

Angle Grout Bag Tip Downward

Angle the grout bag tip slightly downward as you pipe grout for a smoother finish. No excessive buildup.

Run Grout Float Diagonally Over Box

Once the outlet grout is in place, run a grout float at a 45 degree angle over the box to blend.

Use a Damp Sponge for Smoothing

Gently wipe with a damp sponge in circular motions to smooth out grout around outlets.

Don’t Smear Grout Into Electrical Boxes

Be very careful to keep grout out of the interior of electrical boxes to avoid issues.

Let Grout Fully Cure

Just as with mortar, allow grout several days to cure properly before regular use of outlets.

With some finesse and attention to detail, you can achieve flawless grout lines around your outlets.

Completing Electrical Boxes After New Backsplash

You’re in the home stretch! Here are the last steps to finish off your outlets:

Remove any Mortar or Grout Inside Boxes

Use a dry cloth or brush to carefully clean out any excess mortar or grout from outlet interiors.

Prepare New Cover Plates

For a seamless look, install new tile cover plates to match your backsplash. Polish or rough metal plates also work great.

Ensure Proper Setback for Covers

Test fit covers and use spacers if needed to get flush alignment with tiling instead of the box.

Seal Cover Plate Edges

Run a thin bead of clear silicone caulk around edges of the cover plate for moisture protection and a polished finish.

Turn Power Back On!

You did it! Flip the breakers back on and test outlets to make sure all is working properly.

Take pride in your outlet remodeling each time you plug in or flip a switch!

Frequently Asked Questions About Backsplashes and Outlets

Many homeowners have additional questions when installing backsplashes around electrical boxes. Here are some of the most common inquiries:

Should outlet boxes be anchored to the wall?

Yes. Outlet boxes should always be firmly anchored to wall studs or backing for safety and stability during tiling.

What if my tiles are not level with existing outlet boxes?

You can use box extenders to bring outlets flush with the new tile. Take care not to exceed total allowable depth.

Can I adjust an outlet location if needed?

Moving a box over a few inches side-to-side is generally allowed. However, significant relocation may require an electrician.

How do I cut narrow tiles around outlets?

Mark the small cutouts needed, then use a wet saw with a fine tooth blade for intricate cuts on mosaic, subway tile or thin brick sheets.

Should I be concerned about water exposure near outlets?

Proper GFCI protection combined with outdoor rated covers and caulk will prevent issues in kitchens and bathrooms.

How close can backsplash tile be to a cooktop or range?
